Pitchman Pumps

Two Pitchman Pumps named "Regular" and "Premium" sang the praises of Marathon Gasoline in a 1963 commercial called "Out of Town on Business," produced by Jim Henson. The characters featured moving jaws in the handles, and were voiced by professional jingle singers rather than Muppet performers.

In the commercial, the Pumps complain that the gas station attendant gets all the glory. "Who knows better than we do about our feeling of pride?" the Pumps sing. "Cause we've got Marathon gasoline surging inside!" They urge drivers to "give your engine what it wants -- right-now response!"
